+## Support for Maximum File Size
+
+This plugin allows you to specify the maximum file size for attachments by using the `@Validation.Maximum` annotation on the attachments content property. When a user attempts to upload a file that exceeds the defined limit, the upload will be rejected with "AttachmentSizeExceeded" error.
+
+Refer the following example from a sample Bookshop app:
+
+```cds
+
+entity Books {
+  ...
+  attachments: Composition of many Attachments;
+}
+
+annotate Books.attachments with {
+  content @Validation.Maximum : '200MB';
+}
+```
+
 ## Support for Multiple attachment facets
 The plugin supports creating multiple attachment facets or sections, each allowing various documents to be uploaded. The names of these facets are fully customizable. All existing operations available for the default attachment facet are also supported for any additional facets you create.
